Evaporation Of Fluorine, Chlorine And Selenium From Glass Melts And Emissions Reducing Measures

Simultaneous waste gas treatment of inorganic gaseous fluorine and chlorine compounds as well as of gaseous selenium compounds is still a big problem for many companies. With the aid of a (German) HVG/AiF research project, investigations were carried out with the aim of characterizing the evaporation behaviour of fluorine, chlorine and selenium from industrially melted container glass, and of correlating their behaviour with the operating data of the melting furnaces. Main effort, however, was put into investigating the absorption rates on an existing waste gas treatment plant depending on the kind and the quantity of the absorption agent. Moreover, influence of the absorption temperature on the absorption rate was determined.
